Raise, call or fold PF?
UTG+1 range is tight so it isn't a raise for value. Better hands that he is folding may be 99, or he is not folding any better. So it isn't a raise for a bluff too.
Calling for a set value - his stack is not enough, but CO is good. So maybe it is for set value?
Calling better hand for value - I have not experience with it yet because I was micro FR player and never called for value preflop, but I guess it isn't for value, there is not many worse hands in his range.
Folding 88? Hard to believe

UTG+1 may fold there sometimes 99, but also I think he may fold there AJ/AQ, so to take initiative with 88 is not bad. Only bad thing is about the stack size and I think for that reasons I really don´t like 3-bet there with 88. You have to fold if he shoves and have to likely shove yourself a lot of board what only is Q or J high, like J64.
So I would call. Also you don´t only call 88 for set value, but some times you hit board like 347 and can lead out for value or c/r and play for stacks- depends how aggressively would you like to play your 88 at that spot.
